Interference Effect of Shock Wave on Tip Leakage Vortex in a Transonic Variable Nozzle Turbine
International Journal of Turbomachinery, Propulsion and PowerThe tip leakage flow at both sides of the nozzle vane is an important factor for the reduction in turbine aerothermal performance. A strong shock wave is generated at the trailing edge of the nozzle vane under transonic condition, which can interfere ...
